The headlong rush into the hydrogen economy has many unforeseen
consequences. How about increased rates of skin cancer. Read on.

The whole series of posts that addressed the use of hydrogen fuel
cells as batteries detailed all sorts of technical and logistical
problems with the vision.

I think it better to curtail the use of hydrogen in the future
rather than to turn to it as a substitute for clean power that we
can get from SPS.

I think hydrogen makes sense for auto transport, especially when
compared to the current use of hydrocarbons, but not for the
Lovins' "million points of light" decentralization scheme. Also,
assume that the platinum issue is magically solved, it still doesn't
make sense to use fuel cells as a battery when there is a more
environmentally friendly alternative - SPS.

The damage to the atmosphere would be too great. Why proceed on that
path when SPS can reduce envrionmental damage caused by hydrogen.

"The widespread use of hydrogen fuel cells could have hitherto
unknown environmental impacts due to unintended emissions of
molecular hydrogen, including an increase in the abundance of water
vapor in the stratosphere (plausibly by as much as 1 part per
million by volume). This would cause stratospheric cooling,
enhancement of the heterogeneous chemistry that destroys ozone, an
increase in noctilucent clouds, and changes in tropospheric
chemistry and atmosphere-biosphere interactions."

". . .An increase in the mesosphere of H2O derived from H2 could
lead to an increase in noctilucent clouds, with potential impact on
Earth's albedo and mesospheric chemistry. (iii) H2 is a microbial
nutrient, and thus increased partial pressures of H2 over natural
soils might have unforeseen effects on microbial communities."
